More regarding texlive-bin build failure

[Douglas Muir]

Re-reading some of the posts on texlive-bin from earlier this month, especially #48490, 48582, and 48670, I now see that the problem is that /usr/local is not empty.  

I cannot delete the contents of this directory, but in my case the following work-around is effective:

sudo mv /usr/local /usr/local-save
sudo install …
sudo mv /usr/local-save /usr/local
